MCB Wide Web Automatic Butt Splicer

The MCB Wide Web Butt Splicer offers non-stop roll changing for wide paperboard processes. Elegantly engineered and robustly constructed, the Martin MCB Wide Web automatic butt splicer delivers the reliability, safety and ease of use you need for long-term non-stop productivity. As with all Martin products, the MCB-WW Butt Splicer can be application-engineered to fit each process.

Design features of the MCB-WW include:

• Reliable rolling shear splice unit. This patented butt splice unit simultaneously severs the web and irons tape across the splice, producing a tight bond with no overlap. The precision shear wheel and anvil mechanism guarantees a clean cut and no overlap. A second rotary nip applies tape to the backside of the splice.
• Integral roll loading. The MCBWW uses a traversing lift table at each roll position to pick up rolls from the aisle. Laser-assisted roll alignment enables easy and accurate loading.
• Heavy-duty unwind. Each cantilevered spindle holds a full diameter roll up to 8000 LB (3628 KG). The lift table supports the roll during loading and retracts only after the roll support door is closed.
• Inertia compensated tension control. The festoon features Martin’s inertia compensation technology for consistent, accurate tensioning of the web as it enters the process.
